If you have an alternative explaination as to why the results of my experiments hold true,

Then by all means: speak

otherwise you are simply arguing for the sake of argument, and have no foundation from which to stand on.

Omnibus, a question. If we have a ball on a flat surface, does the ball have potential energy due to gravity? presumably it does, because if we could suddenly remove the flat surface or bring it closer to the centre of the earth it would fall? If we could somehow place the ball at the centre of the earth, would the ball then have any potential energy due to gravity? I think not, but i'm not sure. If what I have said is true then I see what you are getting at with the magnetic potential energy, the ball doesn't have to be anywhere near a magnet, if it's magnetic, (eg. iron) it has magnetic potential energy.

@ ACP - at the outer edge of the atmopshere the ball would have its full potential energy. At the center of the earth it would have none. (or if you look at it from our perspective, at the center of the earth it would have (-mgh) potential energy. Meaning we have to put energy into it to get it back up to 'ground level'.

In this case the 'ground' is the bottom of the device (Point A), and the 'groud' is not removed - so the point of lowest gravitational potential is Point A. 

The (classical) Magnetic Potential relates to the flux density across the width of the entire field. So in this observation, yes there is the same Magnetic Potential regardless of where the ball is.

However, the potential energy on the ball is location specific, just as in the gravity example.
